DuoSi,
I have just obtained some of the Form 540 and 541 records for 293 Sqn for the year 1944 (I will have to get the rest asap) and I see that the crew you listed in your earlier post seemed to have stayed together for most of that year at least. They certainly flew a large number of sorties but a only a very small percentage resulted in anything being seen let alone anyone being rescued. I guess thats the way it is with ASR work.
Let me know if you are interested in any details of any of your father in law operations and I will see if I can help.
Regards
QP
